摘要:
金属原子易团聚和缺乏介孔/大孔结构，是目前制约氧还原催化剂性能的主要瓶颈。为了解决上述问题，本文利用聚乙烯吡咯烷酮(PVP)作为前驱体，分别以Zn2(OH)2CO3和Co-邻菲罗啉络合物作为造孔模板和钴源，通过两步热解法制备了具有分级多孔结构的钴氮共掺杂多孔碳催化剂(HPCo-N-C)。系统研究了HPCo-N-C催化剂形貌及结构组成，结果表明邻菲罗啉配位剂的引入有效避免了金属团聚的发生；而Zn2(OH)2CO3造孔模板则促进了分级多孔结构的构建，有利于活性位点暴露与传质进行。HPCo-N-C催化剂在碱性电解液中的半波电位和动力学电流密度分别达到0.877 V和31.23 mA?cm?2，基于HPCo-N-C催化剂组装的锌-空气电池的开路电压明显高于商用Pt/C组装的锌-空气电池，展现出良好的氧还原催化性能与广阔的应用潜力。
Abstract:
The aggregation of metal atoms and the lack of meso-/macroporous structures are currently the main bottlenecks limiting the performance of oxygen reduction catalysts. To address these issues, this work utilized polyvinylpyrrolidone (PVP) as a precursor, with Zn2(OH)2CO3 and Co-phenanthroline complex serving as the pore-forming template and cobalt source, respectively. Through a two-step pyrolysis method, a HPCo-N-C catalyst with a hierarchical porous structure was prepared. The morphology and structural composition of HPCo-N-C were systematically investigated. Results show that the introduction of the o-phenanthroline ligand effectively prevents metal agglomeration, while the Zn?(OH)?CO? pore-forming template promotes the formation of a hierarchical porous structure, facilitating active site exposure and mass transfer. The HPCo-N-C catalyst achieves a half-wave potential of 0.877 V and a kinetic current density of 31.23 mA?cm?2 in alkaline electrolyte. Furthermore, the zinc-air battery assembled with the HPCo-N-C catalyst exhibits a significantly higher open-circuit voltage than that assembled with commercial Pt/C, which demonstrate excellent oxygen reduction catalytic performance and promise application potential.
